The Knoxville Raceway is back to a single night of racing this week with all three sprint car classes in action tonight. As the season nears the midpoint, the points races are starting to take shape. The 410s have the best race with Austin McCarl and Aaron Reutzel trading the lead back and forth the last few weeks. Going into tonight McCarl leads Reutzel by just two points. Jamie Ball is starting to gap the field in the 360s as he holds a 249 point lead over Terry McCarl and Matt Allen has a 63 point lead over Mike Mayberry.
